Abstract

전기자를 고정하고 계자용 영구자석을 회전시켜서 다단계로 회전각도를 전환하는 회전각도전환장치의 원점복귀시 이상음의 발생을 막고, 단시간에 확실하게 원점복귀할 수 있도록 한다.
출력축(6)에 연결하는 영구자석(3)의 극대수의 3배의 수가되는 코일8∼13을 고정자에 권장해서 3상에 결선하고, 이 코일의 3상중 2상을 선택해서 통전을 전환하고, 이것을 제어하는 통전전환제어회로는 전원 투입시등의 초기화시에, 원점위치에 대응해서 통전하는 코일이외의 코일 포함하는 2상의 코일에 소정시간 통전한후, 원점위치에 대응하는 2상의 코일에 통전을 전환하도록 하였다.
